The brownout detector will reset the chip when the supply voltage is approximately
below this level. Note that there may be some variation of brownout voltage level
between each chip.
Only level 7 is supported on ESP32-H21 (~2.96V). Other values would also
affect PCM/LDO/VDD_DIG and are not offered.
